Issue: How can I factory reset the SODAQ ONE v2 board?
Note 1: I’ve recently been working with the SODAQ ONE v2. It worked perfectly in the beginning however, I had suddenly began to face issues while uploading sketches(Arduino IDE). After going through the forum, I learned that it is possible to reset the module just before uploading, by shorting the reset pin and the ground pin. I was able to upload using this method, a couple of times.
Note 2: Later, I factory reset the RN2483 in order to fix this issue using the “sys factoryRESET” command.
After a few uploads, the board stopped getting recognized by any laptop/PC on connecting the USB, Windows/Linux. [USB device not recognized- Windows].
Note 3: I am now using the CP2102 USB-to-TTL converter with the board and the COM port gets recognized, however I am still unable to upload sketches.
ERROR: No device found at COM3
Note 4: I tried upgrading the firmware to v1.0.1 using the Java tool but no confirmation message was displayed.
I just tried updating the firmware using the link you have mentioned. I am getting the following error (same error during uploading any other sketch):

After pressing the reset button twice and trying to upload, I got the following error:
